Acoustic Pig Locating

Online’s systems are the industry standard for pig locating in subsea liquid pipelines.

Our acoustic pinger and receiver systems enable quick and accurate detection of a stalled pipeline pig from either a support vessel or platform resulting in significant savings in vessel, equipment and personnel costs.

Smart Pingers

Series of acoustic pingers developed for use as pig pingers and for other subsea marking and locating functions.

Pinger Receiver Systems

Acoustic receiver systems allowing for quick and accurate tracking and locating of pigs fitted with subsea acoustic pingers. The location of a stuck pig can be identified using diver and ROV held hydrophone solutions including the option to relay the received acoustic signal to the surface via the ROV’s umbilical.
